JP 2004-123155 A

  However, in the above-described conventional cup container with a lid, since the cutting blade stands by above the sealing material, an impact due to dropping or the like is applied to the cup body at the stage before opening, and the sealing material is moved upward by the impact. There is a concern that the sealing material may come into contact with the cutting blade when it expands. Therefore, the subject remains in the sealing performance by a sealing material.

  This invention is made | formed in view of such a situation, The objective is to provide the cup container with a lid | cover which the reliability of the sealing performance improved before opening.

In order to achieve the above object, the present invention provides the following means.
(1) A cup container with a lid according to the present invention has a bottomed cylindrical cup body whose opening is sealed with a sealing material, and a lid that is attached to the cup body and covers the sealing material. A body and an opening member that is disposed above the top wall portion and breaks and opens the sealing material through a through-hole formed in the top wall portion, and the opening member is interposed via a hinge portion. A cutting blade support connected to the top wall, and a cutting blade formed at a tip portion located above the through hole in the cutting blade support and protruding toward the sealing material, The lid is formed with a regulating piece that protrudes toward the inside of the through hole between the cutting blade along the container axial direction and the sealing material, and regulates deformation of the sealing material, and the regulating piece Is formed so as to overlap with the cutting blade in the container axial direction in a plan view seen from the container axial direction. Rutotomoni, characterized in that it is elastically deformable.

According to the cup container with a lid according to the present invention, the cutting blade support is rotated about the hinge portion, and the cutting blade is moved downward toward the sealing material, thereby sealing the cutting blade through the through hole. The material can be contacted. Thereby, a sealing material can be fractured | ruptured and can be opened.
In particular, since a regulating piece protrudes from the lid toward the inside of the through hole between the cutting blade and the sealing material, the sealing material is moved upward by an impact such as dropping at the stage before opening. Even if it swells, the restriction piece restricts the deformation of the portion of the sealing material facing the through hole, and the sealing material can be prevented from coming into contact with the cutting blade. Therefore, it is possible to suppress the occurrence of inconvenience such as opening of holes in the sealing material, and to improve the reliability of the sealing performance before opening.
Further, since the regulating piece overlaps the cutting blade and the container axial direction in plan view, it is possible to more effectively suppress the sealing material from contacting the cutting blade before opening.
Furthermore, even when the regulating piece comes into contact with the cutting blade that moves with the turning operation of the cutting blade support during opening, the regulating piece is pushed and elastically deformed by the cutting blade. Therefore, it is not necessary for the regulating piece to obstruct the breaking of the sealing material by the cutting blade, so that the opening can be performed reliably. Moreover, since a control piece can also be formed so that a cutting blade may be covered widely from the downward direction, the contact with the sealing material and cutting blade before opening can be suppressed more effectively.

(2) In the cup container with a lid according to the present invention, it is preferable that the restricting piece and the cutting blade are connected via a breakable connecting portion.

  In this case, since the regulating piece and the cutting blade are connected at the stage before opening, it is possible to prevent the cutting blade support from rotating unexpectedly and to prevent unintentional opening. Further, by confirming the presence or absence of breakage of the connecting portion, it is possible to grasp at a glance that the tampering or the like has not been made and the unused portion is unused.

  ADVANTAGE OF THE INVENTION According to this invention, it can suppress that inconveniences, such as a hole opening in a sealing material at the stage before opening, can be suppressed, and the reliability of sealing performance can be improved.

It is an expanded sectional view of the cutting blade periphery which comprises the cup container with a lid shown in FIG. It is a longitudinal cross-sectional view which shows the state which operated the lever piece from the state shown in FIG. 1, and fractured | ruptured the sealing material with the cutting blade.

Hereinafter, embodiments of a cup container with a lid according to the present invention will be described with reference to the drawings.
(Configuration of cup container with lid)
As shown in FIGS. 1 and 2, the cup container 1 with a lid according to the present embodiment has a bottomed cylindrical cup body 2 in which contents (not shown) are accommodated and an opening 10 is sealed with a sealing material 5. And a lid 3 having a top wall portion 22 that is attached to the cup body 2 and covers the sealing material 5, and is disposed above the top wall portion 22 and sealed through a through hole 22 a formed in the top wall portion 22. And an opening member 4 that breaks and opens the material 5.

  The cup body 2 has a bottom portion 11 and a body portion 12 and is formed in a bottomed cylindrical shape having a circular shape in cross section. Hereinafter, the axis passing through the center of the cup body 2 (the axis passing through the circular center formed by the cross section) is referred to as the container axis O, the opening 10 side along the container axis O is the upper side, and the bottom 11 side is the lower side. That's it. A direction perpendicular to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

  The body 12 of the cup body 2 is gradually reduced in diameter from the upper side to the lower side. A flange portion 13 that protrudes radially outward is formed on the upper end opening edge of the cup body 2 over the entire circumference. And the sealing material 5 is being fixed to the upper surface of this flange part 13, and the opening part 10 is sealed.

  Examples of the sealing material 5 include a single layer or a laminated sheet of synthetic resin, or a laminated sheet in which a metal thin film layer and a synthetic resin layer are laminated. Moreover, as a method of adhering the sealing material 5 to the upper surface of the flange portion 13, for example, adhesion, pressure bonding, heat welding, high frequency welding, adhesion, and the like can be cited.

  As shown in FIGS. 1 to 3, the lid 3 is connected to the mounting cylinder 20 that surrounds the flange 13 from the outside in the radial direction, and is connected to the upper end of the mounting cylinder 20 and protrudes inward in the radial direction. An annular connecting plate 21 that overlaps the upper surface of the flange portion 13, the ceiling wall portion 22 that closes the inside of the connecting plate 21, and a protruding wall portion 23 that protrudes upward from the connecting plate 21. . The lid 3 is disposed coaxially with the container axis O.

The mounting cylinder portion 20 is undercut fitted to the flange portion 13. Thereby, the lid 3 is detachably attached to the cup 2. However, it is not limited to undercut fitting.
On the lower surface of the connecting plate 21, contact rib pieces 24 arranged at intervals in the circumferential direction are formed in a state where they are also connected to the mounting cylinder portion 20. The connecting plate 21 overlaps the upper surface of the flange portion 13 with the sealing material 5 sandwiched between the contact rib pieces 24.
However, the contact rib piece 24 is not indispensable, and the connecting plate 21 may directly overlap the upper surface of the flange portion 13 with the sealing material 5 interposed therebetween. Further, the contact rib piece 24 may be formed in an annular shape. In addition, when the contact rib piece 24 is formed in an annular shape, the sealing performance between the flange portion 13 and the connecting plate 21 can be improved, which is preferable.

The top wall 22 is formed in a convex curved shape that bulges upward. The top wall 22 is formed with the through hole 22a at a position away from the container axis O.
In the illustrated example, the through-hole 22a is formed in a rectangular shape in plan view in which the length along the radial direction is slightly longer than the length along the circumferential direction. In addition, the outer edge part located in the radial direction outer side among the peripheral parts of the through hole 22a reaches an inner wall 23b described later of the projecting wall part 23, and the inner edge part positioned on the radial inner side of the peripheral part of the through hole 22a is It is located radially outside the container axis O.
The protruding wall portion 23 will be described later.

  As shown in FIGS. 1 and 2, the opening member 4 is formed on a lever piece (cutting blade support) 30 connected to the top wall portion 22 via a hinge portion 32 and a tip portion 30 a of the lever piece 30. And a cutting blade 31 protruding toward the sealing material 5.

  The lever piece 30 has a long shape extending along the radial direction, and is formed to have a length that does not protrude outward in the radial direction from the top wall portion 22. The lever piece 30 has a distal end portion 30a on one end side in the longitudinal direction above the through hole 22a, and a proximal end portion 30b on the other end side in the longitudinal direction sandwiching the container axis O and the distal end portion 30a. Is connected to the top wall portion 22 via the hinge portion 32 so as to be located on the opposite side in the radial direction. In the illustrated example, the lever piece 30 is disposed such that the center portion in the longitudinal direction is located on the container axis O.

  The hinge portion 32 is formed along the inner edge portion of the through hole 22a, and is formed at the upper end portion of the hinge protrusion 33 erected upward from the inner edge portion. Accordingly, the cutting blade 31 formed on the distal end portion 30a of the lever piece 30 is moved downward toward the seal member 5 around the hinge portion 32 by rotating the base piece 30b of the lever piece 30 so as to pull up. It becomes possible to make it.

  In addition, the front-end | tip part 30a of the lever piece 30 of this embodiment is formed in planar view circular arc shape along the circumferential direction, and also the cutting blade 31 is planar-view circular arc shape along the front-end | tip part 30a of lever piece 30. Is formed. Moreover, the longitudinal cross-sectional view shape of the cutting blade 31 is formed in V shape so that it may protrude toward the downward direction, and the front-end | tip part 31a of this cutting blade 31 is sharpened.

Further, the portion of the lever piece 30 that extends from the connecting portion with the hinge portion 32 to the tip portion 30 a is sized to pass through the through hole 22 a formed in the top wall portion 22. Accordingly, the cutting blade 31 can be moved downward toward the sealing material 5 through the through hole 22 a in accordance with the turning operation of the lever piece 30.
Furthermore, an outlet 34 for allowing the contents to pass through is formed in a portion of the lever piece 30 from the connecting portion with the hinge portion 32 to the tip portion 30a. However, the outlet 34 is not essential and may not be formed.

  As shown in FIGS. 1 to 3, the protruding wall portion 23 of the lid body 3 extends along the connecting plate 21 so as to surround a portion excluding the base end portion 30 b of the lever piece 30 described above from the outside in the radial direction. The formed first projecting wall portion 23A and the top end of the first projecting wall portion 23A are folded back from the peripheral end portion to the inside of the container and extend from the base end portion 30b side to the vicinity of the hinge portion 32 along the lever piece 30. And a second projecting wall portion 23B formed on the wall portion 22.

Thus, the protruding wall portion 23 protects the entire opening member 4 and prevents the contents from spilling while securing a rotation space when the base end portion 30b of the lever piece 30 is rotated. Can do. Therefore, the inside of the protruding wall portion 23 functions as a drinking mouth or a spout for the contents.
In the illustrated example, the first protruding wall portion 23A and the second protruding wall portion 23B have an outer wall 23a and an inner wall 23b, and a double wall structure in which the upper end portions of the outer wall 23a and the inner wall 23b are connected to each other. Has been.

The lid 3 configured as described above protrudes toward the inside of the through hole 22a between the cutting blade 31 along the container axis O direction and the sealing material 5 and regulates deformation of the sealing material 5. 40 is formed.
Specifically, the restricting piece 40 is formed so as to protrude radially inward from a portion located on the radially outer side of the distal end portion 30a of the lever piece 30 in the inner wall 23b of the first protruding wall portion 23A. ing. In the example shown in the drawing, the restricting piece 40 is thin and elastically deformable, is formed in a semicircular shape in plan view, and is formed so as to protrude radially inward from the cutting edge 31 in plan view. Thereby, the regulation piece 40 has covered a part (circumferential center part) of the front-end | tip part 31a of the cutting blade 31 from the downward direction, By this, the regulation piece 40 and the cutting blade 31 have overlapped with the container axis O direction, Has been.

(Use of cup containers with lids)
Next, the case where the cup container 1 with a lid | cover comprised as mentioned above is used is demonstrated.
First, as shown in FIG. 4, the base end portion 30 b of the lever piece 30 is pulled up to rotate the lever piece 30 around the hinge portion 32. Thereby, the front-end | tip part 30a of the lever piece 30 and the cutting blade 31 can be moved below centering | focusing on the hinge part 32. FIG. At this time, the cutting blade 31 moves downward along a movement locus L (a rotation locus around the hinge portion 32) shown in FIG. 3 while being elastically deformed so as to push down the regulating piece 40. Then, the cutting blade 31 moved downward passes through the through hole 22a of the top wall portion 22, and then contacts the sealing material 5 and breaks the sealing material 5 as shown in FIG. Thereby, the opening operation | work of the cup container 1 with a lid | cover can be performed.

  After opening, the cup body 2 is tilted so that the contents can flow out through the through hole 22a of the top wall portion 22 and the outlet 34 of the lever piece 30, so that the drinking mouth surrounded by the protruding wall portion 23 Alternatively, the contents can be drunk or poured out using the spout.

In particular, since the lid-equipped cup container 1 of the present embodiment has the restricting piece 40, a water hammer phenomenon of the contents occurs due to an impact caused by, for example, dropping at the stage before opening, whereby the sealing material 5 is formed. Even if it swells upward, the restriction piece 40 restricts the deformation of the portion of the sealing material 5 that faces the through hole 22 a, and can prevent the sealing material 5 from contacting the cutting edge 31.
Therefore, it is possible to suppress the occurrence of inconveniences such as the formation of perforations in the sealing material 5 or the breaking of the sealing material 5. As a result, the reliability of sealing performance before opening can be improved.

Further, as shown in FIG. 3, the restricting piece 40 protrudes radially inward from the cutting edge 31 to cover the tip 31 a from below, and crosses the movement locus L of the cutting edge 31. Therefore, it can suppress effectively that the sealing material 5 contacts with the cutting blade 31 in the stage before opening.
Further, at the time of opening, the restriction piece 40 is elastically deformed by being pushed by the cutting blade 31 as described above, so that the restriction piece 40 does not hinder the breaking of the sealing material 5 by the cutting edge 31 at all. Therefore, even if the regulation piece 40 is formed, the opening can be reliably performed. Since the regulating piece 40 is thin and elastically deforms with little resistance, the turning operation of the lever piece 30 can be easily performed with little resistance.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the regulation piece 40 is formed in a semicircular shape in plan view so as to cover a part of the tip portion 31a of the cutting blade 31 from below, but this is not a limitation. For example, the restriction piece 40 may be formed in an arc shape that is long in the circumferential direction along the distal end portion 31a of the cutting blade 31, and the entire distal end portion 31a of the cutting blade 31 may be covered from below. Furthermore, when the cutting blade 31 has a plurality of sharpened tip portions 31a, it is preferable to form the regulation piece 40 so as to cover all of the plurality of tip portions 31a from below, but the plurality of tip portions The restriction piece 40 may be formed so as to cover at least the tip 31a that protrudes at the lowest position of 31a from below.

  Moreover, you may connect the control piece 40 and the cutting blade 31 via the connection part which can be fractured | ruptured. In this case, since the regulating piece 40 and the cutting blade 31 are connected to each other before opening, the lever piece 30 can be prevented from rotating unexpectedly, and unintentional opening can be easily prevented. Further, by confirming the presence or absence of the connecting portion, it is possible to grasp at a glance that the tampering or the like has not been made and the unused portion is unused.

Furthermore, in the said embodiment, while forming the control piece 40 so that elastic deformation is possible, the control piece 40 is protruded to radial inside rather than the cutting blade 31, and the front-end | tip part 31a of the cutting blade 31 is covered from the downward | lower direction, and the cutting blade 31 is provided. However, the regulating piece 40 is protruded radially inward from the cutting edge 31 to cover the tip 31a of the cutting edge 31 from below, and the movement locus L of the cutting edge 31 is not crossed. It is good also as a structure.
In this case, at the time of opening, when the cutting blade 31 is rotated around the hinge portion 32, the tip portion 31a of the cutting blade 31 and the regulating piece 40 can be configured not to contact each other. Therefore, the restricting piece 40 can be given rigidity, and the swelling of the sealing material 5 can be prevented more reliably. In addition, the lever piece 30 can be rotated more smoothly, and the operation force during the rotation operation is not expended in elastically deforming the regulating piece 40 in the middle. Also, the sealing material 5 can be broken more favorably.
Further, for example, the radially inner end portion of the restricting piece 40 is positioned directly below the distal end portion 31a of the cutting blade 31, and the radially inner end portion of the restricting piece 40 and the distal end portion 31a of the cutting blade 31 are in the container axis O direction. The restricting piece 40 does not need to protrude radially inward from the cutting edge 31 as in the configuration overlapping with the cutting edge 31. Even in this case, it is possible to suppress the sealing material 5 from being swollen upward and coming into contact with the cutting edge 31 at the stage before opening by using the regulating piece 40.
Furthermore, the restriction piece 40 only needs to be positioned between the cutting blade 31 and the sealing material 5. Therefore, the regulation piece 40 and the cutting edge 31 do not have to overlap in the container axis O direction, and the regulation piece 40 protrudes toward the inside of the through hole 22a, so that it faces the through hole 22a in the sealing material 5. It suffices if the deformation of the portion to be controlled can be regulated.

Moreover, in the said embodiment, the lever piece 30 extended along the radial direction is mentioned as an example as an example of a cutting blade support body, By rotating operation so that the base end part 30b of the lever piece 30 may be pulled up, Although the tip 30a and the cutting edge 31 of the lever piece 30 are configured to move downward about the hinge 32, the present invention is not limited to this case.
For example, it may be a cutting blade support in which the base end portion (root portion) is connected to the hinge portion 32 and the cutting edge 31 is formed at the distal end portion. In this case, for example, the cutting blade 32 can be moved downward about the hinge portion 32 by pushing down the tip of the cutting blade support. Therefore, the same effect can be achieved.
